Patent ES-280082-A1 (ES)
Title: Process for the recovery of phosphoric acid from aqueous reaction mixtures produced by the decomposition of tricalcium phosphate with hydrochloric acid
IPC: C01B25/22
Filed: 1962-08-17
Abstract: Phosphoric acid is recovered from the aqueous reaction mixtures produced by the decomposition of tricalcium phosphate with hydrochloric acid in an aqueous reaction system by solvent extraction using an amide of one of the following general formulae <FORM:0953156/C1/1> in which R1, R5, R6, R7 and R8 are hydrogen or a hydrocarbon radical R2 and R3 are hydrogen or a hydrocarbon radical, or R2 and R3 together with the nitrogen to which they are attached form a heterocyclic ring system R4 is a hydrocarbon radical and R9 is a divalent hydrocarbon radical. The extractant solvent may contain more than one of these amides and/or another organic solvent miscible with the amide and which lowers its viscosity. To recover the phosphoric acid from the solvent extract a water immiscible organic solvent may be added and any hydrochloric acid removed from the phosphoric acid in the aqueous layer thus produced. Alternatively the solvent extract may be re-extracted with water and again removing hydrochloric acid from the aqueous solution of phosphoric acid. If desired, the solvent extract may be directly subjected to a thermal treatment, e.g. distilling or stripping to remove the solvent amide and hydrochloric acid from the phosphoric acid. The extraction of the decomposition liquor by the amide is preferably effected at a temperature at which the solubility of phosphoric acid in the amide is comparatively high and then after separation from the aqueous liquor, the temperature is lowered to reduce the solubility. Numerous examples are given.

Patent ES-355027-A1 (ES)
Title: Improvements in or relating to the production of fibrous material from micro-organism cells
IPC: C12P21/00
Filed: 1968-06-05
Abstract: Cells of micro-organisms are extracted with a solvent which consists of or contains formic acid, the extraction being carried out under conditions such that all, or a substantial proportion, of the protein and carbohydrate content of the cells passes into the extract phase, thereafter, any solid phase still present is separated from the extract phase and (whether or not a solid phase has been separated) the extract phase is mixed with an aqueous phase whereby a fibrous material is precipitated and recovered. The micro-organism cells are typically obtained by the aerobic culture of specified normal paraffin-consuming yeasts, moulds or bacteria on a hydrocarbon substrate. Under preferred conditions of operation: the micro-organism is in a dry state when subjected to the extraction, formic acid is employed in the anhydrous state or in aqueous dilution containing at least 80% of formic acid, and the extraction is carried out at a temperature of at least 60 C. with a contact time of at least 2 hours. The extract phase is mixed with aqueous caustic soda solution or sodium citrate buffer to give a pH in the range 3À5 to 4À2, the resulting solid fibrous phase is dried in an oven, and the remaining aqueous phase is spray dried as such, or the proteins are precipitated and a fraction containing the proteins is mixed with the fibrous material, with or without treatment to achieve bonding. According to an example, 100 g. of dry Candida yeast was stirred with 1 kg. of 85% aqueous formic acid at a temperature of 90 C. for 5 hours, and at the end of this period the solution thereby obtained was added to three times its volume of cold water. The mass of solid fibrous material which formed in the aqueous medium was removed by filtration on a 0À5 mm. mesh nylon screen using reduced pressure. The filtered material was dried in a vacuum oven at 45 C., whereby there was obtained 25 g. of a fibrous material having a nitrogen content of 2À7% by weight. The filtrate contained in solution 75 g. of solid material having a nitrogen content of 11%. In a further example, the solution in formic acid was added to N/5 aqueous caustic soda instead of to cold water.
